What is response to antigens?


An antigen is any substance that causes your immune system to produce antibodies against it. An antigen may be a foreign substance from the environment such as chemicals, bacteria, viruses, or pollen. An antigen may also be formed within the body, as with bacterial toxins or tissue cells.

Callus

A callus (tyloma) is a thickening of the skin that occurs in response to excessive, repeated shear or friction forces, commonly due to constant rubbing of the skin. Calluses are similar to corns, but calluses occur when abnormal forces are exerted over a larger area. Certain deformities of the feet, such as crookedness of the toes, may predispose to the development of calluses. Calluses may cause pain, typically a burning sensation. Excessive weight bearing and certain types of shoes are often contributing factors.

Abscess

An abscess is a localized collection of pus that generally develops in response to infection. An abscess is typically painful, and it appears as a swollen area that is warm to the touch. The skin surrounding an abscess typically appears pink or red.

Fever of Unknown Origin

Fever is a protective response to infection and injury. An elevated temperature enhances the body's innate defense mechanisms by making conditions less favorable for infectious microorganisms to thrive. An elevated body temperature, for example, decreases the levels of iron in the bloodstream, thus inhibiting the growth of some microorganisms. People with fevers also tend to eat less and rely more on fat and protein sources for energy, which decreases the blood glucose levels upon which bacteria normally thrive. In addition, there are some microorganisms that are heat-sensitive, and do not grow well at elevated body temperatures.

Hearing and vision tests for children
Babies can respond to sights and sounds from an early age. Midwives and hospital staff carry out a number of tests on every newborn baby. These tests help find any problems that a child is born with. These include genetic (inherited) conditions, such as being born with cataracts, or the results of any infections caught by the mother during pregnancy. For example, there is a small risk that a woman who catches rubella during pregnancy might have a child with a hearing impairment. In 2000 the government announced that every newborn baby in England would have a hearing test during the newborn period. This was implemented by March 2006.

Crying in childhood
Crying is an emotional response to a distressing experience or situation. Children cry for many reasons, and the degree of their distress depends on their developmental levels and previous experiences. Children cry in response to pain, fear, sadness, frustration, confusion, anger, and inability to express their feelings. Crying is a normal response to distressing situations that a child is unable to resolve. When the child's coping skills are exhausted, crying is automatic and instinctual. A growing child eventually learns to express feelings of frustration, anger, or confusion without crying. Parents may find it necessary to establish guidelines to help the child develop appropriate behaviors. Praise the child's ability to delay or withhold crying until an appropriate time and place. Teach alternative behaviors to distressing situations. Encourage the child to "use their words" to explain what is upsetting them. As a child develops additional coping and problem-solving skills, crying will become less frequent. As they mature, boys tend to cry less than girls. Many believe these are learned behaviors.
